Lassie is returning to prime time – in a new GE commer cial airing during Sunday’s Golden Globes on NBC.

The spot, shot in black-and- white to replicate those “Las sie” shows from the ’50s, fea tures Lassie and her master, Timmy, out on a lei surely walk. They’re suddenly stopped dead in their tracks by a snar ling mountain lion; Timmy, of course, is petrified – but the ever-brave Lassie gets up on her hind quarters and turns in some smooth “Crouching Tiger, Hidden Dragon”-type moves to scare off the beast.

The spot, created via high- tech computer imagery by BBDO New York, is for Secu rity Technologies from GE. The Golden Globes air 7-11 p.m. on Ch. 4.

* ABC is ordering four more “Life of Luxury” spe cials – and is looking for a co-host to join Robin Leach.
